The Pee Dee River Basin (also called the Great Pee Dee River)
encompasses twenty-seven (27) watersheds and 3,425 square miles
within South Carolina, excluding the Lynches River and the Black
River (which are part of the Pee Dee River Basin). The Pee Dee
River flows across the Sandhills region to the Upper and Lower
Coastal Plain regions and into the Coastal Zone region. The Pee
Dee River Basin includes over one million acres. There are approximately
3,472 stream miles, 9,969 acres of lake waters, and 1,522 acres
of estuarine areas.
The Pee Dee River flows across the North Carolina/South Carolina
state line and accepts drainage from Thompson Creek, Crooked
Creek, Cedar Creek, Three Creeks, and Black Creek. It then accepts
drainage from Jeffries Creek, Catfish Creek, the Lynches River
Basin, and the Little Pee Dee River, and the Black River Basin
before draining into the Winyah Bay at Georgetown.
